Multiples

This topic would deal with multiples. Multiples of a number are actually the tables of a certain number. If we are talking about multiple of 2 then it is actually the tables of 2. When we have learnt table we have learnt the tables till 10 or 12 that is till 2 multiplied by 10 or 2 multiplied by 12 but actually they are infinite. We can go on finding the multiples of 2 beyond 10 or 12.

Important facts about multiple:

• Natural numbers start from 1 and continues till infinity and all natural numbers are multiple of 1.

• Multiples of any number continues till infinity that is there is no end.

• The first multiple of a number is the number itself

Here are few examples illustrated on multiples:
